Specification of Iietters Patent. Patented u ly 8, 1919.

Application filed August 26, 1918. Serial No. 251,455.

To all whom it may concern:

Be it known that I, LOUIS J. MUELLER,

Jr., a citizen of the United States, and resident of Milwaukee, in thecounty of Milwaukee and State of Wisconsin, have invented new and usefulImprovements in Combined Garbage-Burners and Heaters, of which thefollowing is a description, reference being had to the accompanyindrawings, which are a part of this specification.

This invention relates to improvements in garbage burner and waterheater.'

In many modern homes it is the present practice to burn garbage andother refuse on the premises by means of burners of various kinds. Inorder to properly burn garbage in the most eiiicient manner it isnecessary to completely dry or eliminate the moisture from the garbagebefore burning.

In burning garbage and other waste material it is very desirable toutilize theheat generated from the burning material to heat water forculinary and other household uses.

It is one of the objects of the present invention to provide a garbageburner and water heater which will perform the beforementioned desirablefunctions in a highly eflicient manner and which possesses otherdesirable features which will be later described.

--A further object of the invention is' to provide a garbage burner andwater heater having a water cooled grate for-supporting theg'arbagewhile drying and being consumed thereby performing the two foldfunction of preventing the burning of the grate, and heating the waterwhich passes through the grate for household use. i A further object ofthe invention is to provide a garbage burner and water heater havingmeans for directing the ,hot flame and gases from the fuel properof theheater around all parts of the garbage to thoroughly dry the samepreliminary to ,burning the material. 7

A further object of the invention isto provide a garbage burner andwater heater having a novel form of flue construction which carriessmoke from thefuel proper to the rear and over the top of the garbagewhile the garbage is being dried.

A further object of the invention is to provide a garbage burner andwater .heater having a novel means for controlling the dampers orvalves'of the burner and heater.

A further object of the invention is to provide a gar'bage'burner andwater heater having a water cooled grate so constructed as to permit theconvenient cleaning of the water fines of the grate. 1

A further, object of he inve'ntion is to provide a garbage burner andwater heater in which the parts are in the form of sections' which maybe easily assembled. together to form the complete 'structure or takenapart for repairs. 3

With the above and other objects in view the invention consists of theimproved garbage burner and water heater and its parts and combinationsas set forth in the claims, andall equivalents thereof.

In the accompanying drawings in which the same reference charactersindicate the same parts in all of the views: I

Figure 1 is a side view, partly in. section, of the improved garbageburner. and water heater;

Fig. 2 is a vertical sectional View taken on line 22 of Fig. 1; I I

Fig. 3 is an outer side view, on alarger scale, of the upper portionoffthe garbage burner and water heater; I

Figxl is a top view of a modified form of garbage holding. grateportion, parts shown in section; and,

Fig. 5 is a sectional detail view. thereof taken onfline 5-5 of Fig. 4.

Referring to the drawingsthenumeral 8 indicates the base'or ashjpitsection, 9'tlie fuel burner and water heater section and 10 the garb-agechamber section; I

The basesection is .of circular form in cross section and tapersslightly downwardly-to a larger diameter to form a more firm support.The, base section is provided with the usual door 11- for removing ashesfrom said section and with a draft door 12 for supplying air to.the'burner. An annular opening portion of the'base, sectionto receivethe annular lower flange 14: ofthe fuel burner sec tion 9 and hold andsupport said burner section on the base section. Said burner section 9is formed with an inner and an outer wall 15 and 15 spaced apartto forman annular water chamber 17 which surrounds the chamber .in which thefuel is ends and the lower portion of the section 1s provided with afuel grate 18forsupporting the fuel for drying the garbage. The upperend portion of the burner section forms a garbage holding grate 19 andcomprises transversely extending tubular grate bars 20 which areconnected to the opposite sides of the burner section and are incommunication withsthe-water chamber 17 so that water is free to flowtherethrough. The said tubular bars are of rectangular shape in crosssection and are spaced sufficiently close to support the garbage and atthe same time provide sufficient space between the bars for Elle passageof the hot gases to dry the garage. p

The section 9 has a charging opening 21 and an extension passage 22 incommunication therewith and carrying a door 23, the fuel beingintroduced in the chamber through the passage 22 and opening 21, For thepurpose of cleaning the grate a passage 24 is formed in the section 9and an extension passage '25 is secured to said section and carries adoor 26 whereby access may be had to the grate 18.

In Figs. 4 and 5 of the drawing I have shown a modified form of watergrate for supporting the garbage consisting of a concentrically disposedannular tubular portion 27 in communication with the upper portion ofthe chamber 17 through radial passages 28 and a diametrically extendingchannel 29 in line with some of the radial passages 28. I

In either construction the water to be heated is introduced into thechamber 17 and grate through one of the openings 30, the other openingbeing closed by a plug 31- and is carried away through one ofthe-openings 32, the other opening being closed bya plug (not shown).The upper openings 39 are so located with respect to the hollow gratesections as to permit of the introduction of a cleaning tool or deviceto remove'boiler scale collecting in the tubes of the grate.

The garbage section 10 has a conical wall 34 with an annular recessedlower edge 35 and flange 36 resting upon the top of the section 9 andsecured thereto by bolts 37. The wall 34 has a side opening 38 throughwhich garbage is introducedupon the grate, which opening is normallycovered by an outwardly and downwardly swinging door 39. The section '10has a closed top portion 40 provided with a centrally disposed flangedoutlet 41 and a 'fiue 42 which communicates with the upper portion ofthe garbage chamber through an opening 43 in the wall 34 and at itslower end communicates with the upperportion of the combustion chamberbe low the garbage grate through an elbow pipe fitting 44 and anoutletpassage 45 in the upper portion of the section 9.

To provide for efficient drying of the garbage upon the grate radiallydisposed inthrough the wardly extending ribs 46 are secured to theinterior of the wall 43 and forming channels, to permit the products ofcombustion to pass garbage and prevent packing down of the garbagearound the rim of the grate.

The inlet 47 to the flue 42 is provided with a damper valve 49 and theoutlet 41 is provided with a damper 48 and means are provided forsimultaneously moving the valves 48 and 49 consisting of a lever 50pivotally connected to one arm of a bell cranklever 51 pivotally mountedon the section 10 and a link 52 pivotally connected to the other. arm oflever 51, and means for operatively connecting the lever 50 with thevalve 48 and the link 52 with the valve 49. The valve 48 is providedwith a rod 53 having a cranked end 54 which is slidably mounted in anareshaped slot 55 in the lever 50 so that a back and forth movement ofthe lever 50 will cause a turning of the rod 5 3 and the valve 48. Thevalve 49 is provided with a rod-56 having a cranked end 57 which isslidably mounted in a slot 58 in the link 52 so that an up and downmovement of said'link through a swinging of the lever 51 by the lever 50will turn saidrod 56 and the valve 49. To secure the valves in difierentpositions of adjustment the lever 50 is provided with notches 50 adaptedto be brought into locking engagement with a guide bracket 59 mounted ona lug 60 011 the section 10. With this construction the valve '49 isclosedwhen the valve 48 is in about half open position and when thelever 50 is moved to bring the valve 48in full open position the valve49 is in full open position as shown inFigfil.

With this construction afire on the grate 18 insures a constant supplyof hot water and the garbage isfirst dried on the garbage supportinggrate andthen consumed, the burnt garbage bein free to fall through thegrate into the re below. In drying the garbage the valve 49 may be shutoff so that the products of combustion from the fire on the grate passbage on the grate 20 or'the valves 48 and 49 may be opened so that theproducts of combustion pass upwardly through the garbage and alsothrough the flue 42, and over the top of the garbage and outthe'outlet-41. The device thus serves as an eificientwater heater andgarbage consumer and the garbage is utilized as fuel to heat the water.
